Git branch name in prompt

Question

I am able to show the git branch name in the shell prompt. But whenever I am using screen I am getting

bash: parse_git_branch: command not found

and git branch is not shown. Please help me get this in the screen sessions also.

I have following in my .bash_profile.

parse_git_branch() {
    git branch 2> /dev/null | sed -e '/^[^*]/d' -e 's/* \(.*\)/ (\1)/
}

export PS1="[\W\$(parse_git_branch)]$ "

I don't have .git-completion.bash

System specs:

OS: OSX 10.8.4
Terminal & iTerm2
Screen version: 4.00.03 (FAU) 23-Oct-06

How are you customizing your prompt? Could you give your PS1 string? — Nick Tomlin, Jul 23 '13 at 13:22
Where is the `.git-completion.bash` file sourced in your main shell (i.e. without screen ?) — Guillaume Darmont, Jul 23 '13 at 14:15

I had the same issue when running under screen and was able to resolve by moving the definition of the parse_git_branch() function from .bash_profile to .bashrc.

It can be moved or copied from `.bash_profile` to `.bashrc`. I resolved this issue by copying the function. – Yonggoo Noh Apr 23 '16 at 23:35

When you open your terminal, .bash_profile is executed and therefore PS1 is defined. Then you execute screen, and screen reads the environment variable PS1 which includes a call to parse_git_branch and tries to parse it. But, since screen didn't execute .bash_profile the function parse_git_branch is not defined inside screen.

Move the definition of PS1 to .bashrc because both, screen and iTerm execute it.

This is much simpler and avoids the unnecessary sed:

parse_git_branch () {

    while read -r branch; do
        [[ $branch = \** ]] && current_branch=${branch#* }
    done < <(git branch 2>/dev/null)

    [[ $current_branch ]] && printf ' [%s]' "$current_branch"

}

You are missing a ' at the end of your sed statement:

parse_git_branch() {
    git branch 2> /dev/null | sed -e '/^[^*]/d' -e 's/* \(.*\)/ (\1)/'
}
export PS1="[\W\$(parse_git_branch)]$ "

Othewerise, it seems to work for me in bash-3.2

unfortunately it is not working for me. Do I have to add something in the screenrc too? – user2610733 Jul 26 '13 at 17:29
are you still getting the "command not found" message? What else do you have in your .bash_profile? For fun, try putting a test function in your ``.bash_profile`` `` testFunc () { echo "test!" }`` and calling it. – Nick Tomlin Jul 26 '13 at 18:16

I resolved it. once I am in screen I use 'source ~/.bash_profile'. It brings all the settings back. Thanks for the help. – user2610733 Jul 27 '13 at 20:13

I had the same error in OS X High Sierra when switching to root or when starting to ssh-agent /bin/bash I resolved it to put it in /etc/bashrc with check if i am root

if [[ $UID == 0 ]]; then
        PS1="\[\e[1;31;40m\]\u@\h \W\[\e[0m\]\$ "
else
        parse_git_branch() {
                git branch 2> /dev/null | sed -e '/^[^*]/d' -e 's/* \(.*\)/ (\1)/'
        }
        PS1="\u@\h \[\033[32m\]\w\[\033[33m\]\$(parse_git_branch)\[\033[00m\] $ "
fi
